I can't see it being a problem, as its a prescription medication. I wouldn't take tons of it though, just enough for what you need. If you are travelling with a woman, might be an idea to ask her if she'd be willing to carry it, as I doubt a woman would get grilled about why she might need it, if customs were to open her case and find it.

I'd personally not even risk anything and just post a package to yourself, unlabelled without a return address and if a return address is needed, make up a name. The USA is quite strict on AAS, I wouldn't risk.
